▼ In order to satisfy the huge demand energy transmission in future, the DC grid concept is proposed based on voltage sourced converter (VSC) HVDC and modular multilevel converter (MMC) HVDC technologies. It provides an attractive approach for long distance power transmission such as offshore renewable energy transmission in Europe. However, there are two main obstacles in the DC grid development. The first obstacle is the DC fault detection and selective isolation. Under severe fault condition, the DC grid is desired to isolate the healthy and faulty part which implies the whole grid system will operate normally during the fault. The second obstacle is the voltage stepping in DC grid system. The high power converter is desired to achieve high voltage stepping ratio yet must be cost-effective. In this thesis, an IGBT-based DC/DC converter employing an internal inductor-capacitor-inductor (LCL) passive circuit is presented to overcome above two obstacles. The proposed converter can achieve high voltage stepping without internal AC transformer implying smaller converter size and it is also designed to have reasonable efficiency in high power application. In addition, the converter has good response even under extreme fault conditions. The IGBT-based LCL DC/DC converter design procedure and performance under fault condition is investigated based on the theoretical studies initially. The converter is modelled on PSCAD platform under normal/fault operation and the simulation results are used for converter efficiency calculation and fault analysis. The advantages of IGBT-based LCL DC/DC converter are demonstrated by comparing with other two high power DC/DC converter topologies. A low power level prototype of LCL DC/DC converter is built following the design principle. The hardware results are used to verify the theoretical conclusions. The VSC converter is defenceless to DC faults in DC grid application. In order to overco The VSC converter is defenceless to DC faults in DC grid application. In order to overcome this major drawback, a fault tolerant VSC converter employing LCL passive circuit is studied in this thesis. The LCL VSC converter design principle is presented by analysing the converter equations. The converter model is developed on PSCAD platform under normal/fault operation. An advanced control method is designed based on developed MATLAB analytical model to improve the LCL VSC converter stability. The advantages of LCL VSC converter are presented by comparing with its performance with conventional L-VSC converter considering efficiency and fault response. A fault tolerant DC grid topology employing LCL VSCs and using low speed protection is also investigated in this thesis. The simple mechanical DC circuit breakers are used at DC bus bars and at connecting points of each DC cable. A comprehensive protection scenario including DC cable differential protection, DC bus bar protection and back up protection is employed to protect the whole DC grid against any probable DC faults. An accurate DC cable model is…

M.Tech. (Electrical and Electronic Engineering)

With the increasing use of nonlinear loads in power systems, harmonic pollution becomes more frequent with disastrous consequences on the electrical network and other loads. Harmonic currents cause problems such as system resonance, protective relays and switchgear malfunction, communication interference, incorrect meter, equipment and process failure, over heating of transmission and distribution systems, insulation degradation and power transformer failure. It appears therefore absolutely essential to determine the current profile of the loads connected to the same Point of Common Coupling (PCC). This study aims to assess a distorted power system in order to determine the characteristics components of distorted waveforms (DC components, fundamental and harmonics components), and to quantify the respective distortion contributions in the power network. The numerical method is applied to analyse the current waveforms captured with the aid of the digital scope meter (DSO) 1200 series at different sections of the network. The power network under study is designed, constructed and analysed with the MatLab/Simulink 7.0 package. In both methods, the Individual Harmonic Distortion (IHD) and the current total harmonic distortion (ITHD) for the line, the non-linear and linear loads are computed for the harmonic components 5th, 7th, 11th and 13th. The results showed that for the analysis of the power system, numerical analysis based on the resultant harmonic curve method and the MatLab/Simulink as applied to the network all converged to highlight that harmonic components appear both on the line, the PCC and the linear load. This is due to the fact that the converter characteristic harmonics (5th, 7th, 11th, 13th…) are found in the network components (line, PCC, linear load…). The resultant harmonic curve method indicated a randomly distributed percentage IHD in different sections of the network for harmonic orders higher than 7th, whereas the Matlab/Simulink results normally show a non-uniform decay pattern of the IHD as the harmonic order increases within the respective section of the network.

▼ A stable and reliable electrical power supply system is an inevitable pre-requisite for the technological and economic growth of any nation. Due to this, utilities must strive and ensure that the customer’s reliability requirements are met and that the regulators requirements are satisfied at the lowest possible cost. It is known fact around the world that 90% of the customer service interruptions are caused due to failure in distribution system. Therefore, it is worth considering reliability assessments as it provides an opportunity to incorporate the cost or losses incurred by the utilities customer because of power failure. This must be considered in the planning and operating practices. The system modelling and simulation study is carried out on one of the district’s distribution system which consists of 132 kV, 66 kV and 22 kV network in Aliwal North Sector ECOU. The reliability assessment is done on the 22, 66 and 132 kV system to assess the performance of the present system and predictive reliability analysis for the future system considering load growth and system expansion. The alternative which gives low SAIDI, SAIFI and minimum breakeven costs is being assessed and considered. The reliability of 132 kV system could be further improved by constructing a new 132 kV line from a different source of supply and connecting with line coming from another district (reserve) at reasonable break-even cost. The decision base could be further improved by having Aliwal North Sector context interruption cost. However, the historical data which may be used in Aliwal North Sector to acquire interruption costs from the customers are being proposed. The focus should be on improving the power quality on constrained networks first, then the reliability. Therefore, for the Aliwal North power system network it is imperative that Eskom invest on the reliability of this network. This dissertation also analysed load reflected economic benefit versus performance expectations that should be optimized through achieving a balance between network performance (SAIDI) improvement, and total life cycle cost (to Eskom as well as the economy). Reliability analysis conducted in this dissertation used Aliwal North power system network as a case study; the results proved that the system is vulnerable to faults, planned and unplanned outages. Reliability evaluation studies were conducted on the system using DigSilent software in conjunction with FME. These two models gave accurate results with acceptable variance in most indices except for the ENS where the variance was quite significant. It can be concluded that DigSilent results are the most accurate results in all three reliability evaluation scenarios for the Aliwal North Power System, best interpretation being that of DigSilent.

▼ Traditionally, harmonics are ignored in overall efficiency and energy usage studies. However, in the modern era, power systems contain levels of harmonics which can no longer be ignored by engineers, planners, energy conservationists and economists. The directions of power flows have to be considered when harmonics are present in the power network. A methodology and new formulae for individual and overall efficiency and energy usage is developed at each frequency (f1, h and H) and forms the main contribution to research in this field. Two case studies were conducted; a measurement based laboratory experiment set-up and a simulated case study. In the set-up, measurements of current, voltage and power at different points in the network for the 1st, 5th and 7th frequencies were taken. Current and voltage results were used for hand calculations to prove the measured power flows and directions. The measurements were taken with a Fluke 345 three-phase harmonic power quality analyzer. For the simulated case study, a network was investigated using the DIgSILENT and SuperHarm software packages. Their results were compared and it was found that DIgSILENT is the preferred package for power results. It was found that the total harmonic distortion limit for voltage in the simulated network exceeded an acceptable level. The harmonic mitigation solution chosen was to design a passive filter to decrease the distortion by shifting the resonance point of the network. The method to design the passive filter and its impact on efficiency and energy usage is included in the thesis. Unique power flow direction diagrams are developed as part of the methodology and form an essential step in the derivation of the new formulae. Efficiencies, power losses and energy usage at individual and combined frequencies were determined. Results showed the negative effects of harmonics on overall efficiency, energy usage and power losses of the system. The methodology and new formulae developed was found to be effective and their application is recommended for use by industry.

M.Ing.

This study investigates the limits to which distortion can be compensated in electrical distribution networks. Many factors hinder the "ideal" compensation of the line current to a perfect sinusoidal, in phase, scaled replica of the supply voltage. The different power theories that can be used to derive the reference compensation current, is one of the fundamental limits. The differences and correspondences between the FBD and Czarnecki theories are investigated in detail. Furthermore, it is shown by simulation and practical results, that the effectivity of compensation by the instantaneous power theory is load dependent. The compensation strategy and topology also impose limits on the effectivity of compensation. The position and strategy of a compensator determine whether the consumer is able to isolate his distortion from the rest of the network, or isolate himself from the distortion of other consumers. Distortion frequencies and system impedances are chosen specifically to visually show the effect of the different topologies and strategies, by means of simulation. One of the most important limits brought about by new technology, is the lagging of the reference compensation current, due to the use of signal processing in determining the reference signals. The effect of this lagging reference is clearly shown by means of simulation and practical compensation systems. An effectivity index for this phenomenon is defined for steady state systems. The dynamic limitations of this lagging reference compensation current is investigated thoroughly. A method is derived by which the maximum fault, due to the sampling time and signal processing time, can be calculated when a high f-region occurs in the line current. The dynamic response of the compensation system is also limited by the ' di-ability of the converter. Therefore, a method is developed to calculate the individual fault contribution of the lagging reference as well as the converter. This method enables designers to determine the parameters of the signal processing system and the converter in the planning phase. The use of a maximum sampling frequency is stressed. In the experimental work, a 10kVA, PWM-switched IGBT inverter is used as a parallel voltage fed compensator. It compensates for two non-linear loads : a three phase diode rectifier with an inductive load, and a three phase diode rectifier with a capacitive load. The practical compensation according to the instantaneous power theory of these two loads, confirms that the result of this compensation is load dependent. The effect of the lagging reference compensation current in a practical system is also shown.

▼ ENGLISH ABSTRACT: The solar photovoltaic (PV) industry has seen an exponential growth over the last decade, prompted mainly by government incentives and -regulations. Although the global PV industry is dominated by large, utility-scale PV plants, there has been an increase in the uptake of distributed generation (DG) in the form of residential-, commercial- and industrial rooftop PV systems. Globally, utilities are confronted with the issue of integrating DG into electrical distribution networks. The introduction of DG via renewable energy technologies will cause a metamorphosis of conventional passive power systems into active power systems. DG will influence the technical characteristics of conventional power systems, posing technical challenges with regards to operation and control of the power system. This project investigates network integration of distributed rooftop PV systems on three distribution networks (one residential, one commercial and one industrial) in Cape Town, South Africa. The residential and commercial networks are owned and operated by the City of Cape Town Municipality, whereas the industrial network is owned and operated by Eskom, the South African national electricity utility. Amidst the lack of a South African national standard with regard to distributed PV installations, the aim is to start to fill a void in the understanding of PV network integration, in order to provide Eskom and CCT, as well as other local municipalities, with a better understanding of the technical effects of PV on distribution networks, as well as the PV hosting capacity of these distribution networks. This project develops a methodology that can be used to model the technical influence of randomly distributed solar PV uptake on electrical distribution networks. This study focuses solely on the technical effects of voltage rise and equipment overload as network constraints for allowable PV uptake. The methodology first develops techniques with which to model network topology, -loads and PV generators. Subsequently, a simulation methodology is developed and applied to the distribution networks by means of algorithms developed in Digsilent Programming Language. For the residential- and industrial area, the amount of PV-eligible roof space provides potential PV generation capacity that far exceeds the load requirements of the area. It is shown that allowable PV installations on the residential LV networks vary between 187 kW - 373 kW, and allowable PV penetration levels vary between 82% - 150%. Conductor overload and overvoltage constrain allowable PV uptake on the residential LV networks, whereas the residential MV/LV transformers provide adequate capacity to handle much higher PV penetration levels. The industrial network has the lowest allowable PV penetration level (31 %) due to transformers being overloaded by large PV systems. The commercial area experiences no limit to the uptake of PV, since there is not enough PV-eligible roofspace, and subsequent potential PV generation capacity, to cause network… Advisors/Committee Members: Rix, A.

▼ Recently, due to concerns about the liberalization of electricity supply, deregulation and global impact on the environment, securing a reliable power supply has become an important social need worldwide To ensure this need is fulfilled, detailed investigations and developments are In progress on power distribution systems protection and the monitoring of apparatus which Is part of the thesis. The main objective of a protection schemes is mainly to keep the power system stable by isolating only the affected components or the section of the electricity network in which the fault has developed while allowing the rest of the network to continue operating. It is important to note that the protection equipment does not prevent faults from occurring, but it limits the damaging effect of the fault and protects other healthy equipment. This is only achieved if the protection system of the electrical network involved complies with the requirements and purpose of the electrical protection standards. These requirements include the Operational speed, Reliability, Security and Sensitivity. In conventional substations that are still existing Within the utilities networks, a number of long cables are then used to complete the links between substation equipment in order for them to communicate (hardwired). This method is uneconomical and is being phased out completely in the near future. Over the last few years a new standard for substation automation communication has been developed Within the International Electrotechnical Commission (IEC), the IEC 61850. This standard defines the integration requirements of multi-vendor compliant relays and other lED's for multiple protection schemes as well as control and automation techniques. In this particular thesis, Distribution protection is the area of interest, particularly the application of Time and Overcurrent protection schemes. A look into different protection alternatives and the application of new technologies for Electrical Power Distribution Systems that unify protection and control units so that they can be incorporated into Intelligent Substation as opposed to the most existing (conventional substation) is analyzed. The proposed algorithm has been verified through simulations of the CPUT and Eureka three phase power distribution systems. A testing Lab is also part of this thesis and Is meant for experiments as well as simulation performance in order to gain knowledge and skills for designing and engineer substations with lEG 61850 standards equiprnents. The results indicate that the reduction of copper wiring cable has increased and the communication speed has improved and simplified.

▼ In the 21st century, humanity’s thirst for an energy intensive lifestyle has led to the saturated expansion of the modern day power system. As the power system expands, centralised generation philosophies are rapidly being constrained due to increased technical losses. The inability to balance technical, economic and environmental conventional generation needs place further strain on the power system. This constraint has catalysed the emergence of decentralized renewable energy sources. Distributed generation supplements the electrical needs of a rapidly expanding demand for energy and minimises the adverse environmental impact of fossil fuel power stations. Distributed Generation is defined as electric power generation units connected close to load centres. Distributed generation can be classified according to rating, purpose, technology, environmental impact, mode of operation and penetration. Optimally connected distributed generation have many advantages over classically supplied power systems. Such as reduced power losses, improve voltage support and reliability to the system. Deferring network upgrades by relieving congestion and reducing greenhouse gas emission being some of the benefits of integrated distributed generation. This research delivers an optimal placement method of solar photovoltaic distributed generation on a 56 bus utility network to reduce power losses. Critical electrical factors for optimal placement of distributed generation to reduce power losses are defined. A practical loss optimization technique for optimal placement of distributed generation on meshed networks is defined. The technique follows an approach of ranking, profiling, activating, evaluating and finally selecting the optimally placed distributed resources. The importance of reactive power compensation is examined when integrating distributed generation onto meshed networks. Pre and post distributed solar photovoltaic generation placement shows the worsening phase angles leading to poorer power factors. The research demonstrates the impact of penetration and concentration of distributed generation on power system losses. Highly concentrated placement of non-dispatched distributed generation units lead to increase in power losses. Results conclude that the placement of distributed generation for loss reduction on a meshed power system is optimally located to match load-profiled centres. This research is significant as power utility engineers can now benefit from a wider range of skills to assess the impact of DG connections. Advisors/Committee Members: Davidson, Innocent Ewean.

▼ Distributed generation (DG) has been reincarnated after its demise by centralised generation. While economy of scale and efficiency are the advantages of the latter, deregulation of the electricity market, environmental concerns and the need to arrest dwindling reserve margins have necessitated the rebirth of the former. Indeed, a full circle has therefore evolved with generation being ‘embedded’ in distribution systems and ‘dispersed’ around the system rather than being located and dispatched centrally or globally. This development is in tandem with the history of industrial revolutions that started from energy and moved through services and communication and back to energy. South Africa is not immune to the global energy, especially tertiary energy, challenge phenomenon. At the peak of the 2007-2008 energy crisis, her generation net reserve margin fell below 10% – well below conventional industry benchmark of at least 15%. Also South Africa is Africa’s largest emitter of CO2 contributing over 40% of Africa’s total CO2 emissions. Therefore, DG’s relevance to South Africa is quite obvious. However, DG integration into distribution networks leads to a number of challenges. For instance, with significant penetration of DG power flow reversal may be experienced and the distribution network will no longer be a passive circuit. This underscores the crucial role of ICT in active distribution network occasioned by DG and especially the emergent of “prosumerism” (a hitherto consumer also becoming a producer). Therefore, a smart grid and similar phrases have all been used to describe a “digitised” and intelligent version of the present-day power grid. There are immense benefits derivable from modelling and simulation. Consequently, a typical radial distribution network model has been developed to evaluate the considerable impacts of DG integration. The modelling and simulation of the network are accomplished using the DIgSILENT PowerFactory simulation package. Impacts of DG on voltage profile, fault level, voltage stability and protection coordination have been investigated and their possible mitigation measures proferred. The results reveal that for a particular DG type its impacts depend mainly on its capacity and point of connection relative to a given load type. Smart grid technology addresses some of these impacts through its inherent capability which includes peer-to-peer relay communication for protective devices on the distribution feeder as well as communication to the DG facility.

▼ This dissertation represents the design and development of a load management system for fixed appliances in a safe direct current (DC) Reconstruction and Development Programme (RDP) house. A combination of valley filling, load shifting and peak clipping load management techniques were employed to assist in reducing the peaks observed in the RDP house load profile during peak hours. A DC RDP house laboratory model was developed. The study is based on the assumption that the normally 220 V alternative current (AC) grid is replaced by a 350 V DC grid. The assumption is thus that 350 V DC is available at the distribution box in the RDP house laboratory model. All theoretical work was based on a 350 V DC system, but due to the lack of a laboratory 350 V DC supply, all physical tests were conducted by making use of a 300 V DC supply which was available. Consequently all calculations were thus based on 300 V DC as well. The geyser was the main fixed appliance focused on since it contributes to a significant portion of the power used. An AC geyser was successfully modified in order to be used in the DC network. Safety of the system was considered in order to interrupt the power in case of overcurrent or to isolate the power. Electronic switches were also developed and implemented to ensure that the DC power could be safely switched on and off and that the low power DC was isolated from the high power DC. LabVIEW allowed all other appliances in the DC RDP house to be virtually represented so that a holistic view of the power use of the house could be represented. This also allowed the system to be successfully simulated before any physical work was conducted. The load management system was successfully implemented by making use of power line communication. This proved to be a cost effective means to apply the load management algorithm. The algorithm consisted mainly of power on / off instructions that were executed during peak and off-peak times. It follows the normal use of timers used in the AC system to help reduce demand. It was found that the load management system successfully reduced the demand during peak hours without compromising the basic needs of the user. The power line communication modem proved to be very reliable in implementing the load management algorithm. Advisors/Committee Members: Wheeler, Jacques (advisor), Raji, Atanda K (advisor).

▼ Economic growth that leads to sustained increase in electricity demand resulted into extension of AC systems. This is due to the correlation between the increase in population and power consumption. It was anticipated that by now the power consumption in developing and emerging countries is expected to have increased by 220%. When such happens the power system will be experiencing problems of uncontrolled loop-flows, overloading and excess of short circuit levels, system instabilities and outages. In order to ensure the continuity of supply, power system enhancement and interconnections needs to have been in place in a form of higher voltage levels, new transmission technologies and renewable energies. As anticipated, power consumption increased to the point where power systems are constrained. The purpose of the study is to enhance the inherent power transmission capacity of the overhead lines on the overloaded existing sub-transmission and distribution networks. FACTS have been developed with the aim to better load flow and voltage control. However the devices help in increasing transport capacity, in avoiding loop power flows, in improving transient and dynamic stability etc but do not increase the inherent transmission capacity of a line. Point-to-point VSC-based HVDC transmission was used as an alternative to upgrade the existing right of way corridors. This was achieved by transformation of an existing AC line with a DC one, making maximum use of conductors and towers with up to 4 times transfer capacity increase. The studies were modelled in the software tool Digsilent Power Factory. Three scenarios were simulated under short circuit and contingency conditions where voltage was being monitored on the bursars and the capacity together with overloading were monitored on the HV lines of substations. In chapter one, the background objectives and significance of the study are presented followed by the insight on to classic HVDC transmission networks in chapter two. This matured technology was studied to trace the increased potential of HVDC applications. VSC-based converters are presented in chapter three. Amongst others, the dynamic voltage support, the system stability and the higher power transfer capacity offered by VSC based converters were the most beneficial pertaining to this thesis. Due to challenges encountered in acquiring the land for new electricity infrastructure. It has been noted that urban electrical system require easy solutions that can be attained within urban boundaries and shot lead times.as a consequence the replacement/conversion of existing AC overhead lines with DC is presented in chapter four. Among the system instability problems encountered on the network at study, Voltage instability was a key issue to be addressed and chapter five presents categories of voltage stability and mitigations thereof. In chapter six the modelling and simulation of the existing AC network to underpin the problem statement for different contingencies is presented. The results are recorded so that they can be… Advisors/Committee Members: Raji, A.K., Dr (advisor).
